Why is the power of air conditioning on small displacement vehicles insufficient?

The engine power of small displacement vehicles is relatively small. When the air conditioner is turned on, the air conditioning system needs to consume part of the engine power to drive the compressor and other equipment, resulting in the reduction of the effective power of the engine and insufficient power. In addition, the air conditioning system will increase the total load of the car, thus further reducing the power output of the engine. Especially in high temperature environment, the air conditioning system needs to consume more power to keep the temperature inside the car, so it is easy to cause insufficient power. Therefore, for small-displacement vehicles, it is best to control the frequency and time of turning on the air conditioner when driving in hot weather, so as not to cause too much impact on vehicle performance.
